My invention relates, to hygienic shaving 4 brushes comprising sets or'bunches of bristles which are inclosed in a protecting sheath and:

the readyinsertion and removal of the sets of bristles and will also prevent the use of V the operation, by reason of the small cross a the bristles a second time. 7 a

The bristles (or fibres) are held together before use by means of a metal ring attached by clips, or by suitable binding members such as Wires, braiding, paper rings or the like. To properly mount the bristles in the.

handle so that none of them will escape from the bunch, the said handle should exercise vided with a tapered spindle.

Fig. 1 is a modified form of spindle.

Figs. 2 and 3 represent modified forms of this device.

In Fig. 1, 1 is the handle properly so called,

into the lower end of which is screwed the spindle 2 maintained bythe pin 3. i

The said spindle comprises a screwthreaded part 4 engaging a'tapped sleeve 5 which is mounted by easy friction upon the end of the handle 1; the end 6 of said spindle is tapered and screwthreaded, and this end is adapted for insertion into the bunch of bristles (or fibres) 7 Whose bottom part is fitted into the recess 5 formed in the sleeve 5. The interior of the sleeve 5 is preferably striated to prevent the rotation of the bristles when the spindle 2 is screwed in place. I

In this device, it will be noted that during the insertion of the tapered end 6' into the set Fig. 1 is an axial section of a handle proofbristles, these latterwill expand and will cause their maintaining ringfi to burst, so

that the-said ringwill ibejammed upon its entire peripheryv againstthe inner striated surface of the recess 5. -The screw-thread should have the same pitch for the part4 and for the end 6, so as to prevent all relative motion oftheaset of bristles and the sleeve 5 f when the device is screwed. a

Sincethe tapered end 6 is more readily inserted into the bristles at the be innin of section of the tapered end, adjacent the point, I may, in order to screw the device more rapidly, adopt for the coacting parts 4 and 6 a variable pitch which is greater nearthe point than at the other end. I may further provide upon the tapered part (Fig. 1) a multiple screw-thread, and on the part 4 a single screw-thread Whose pitch is that of the thread of the said tapered part, since experience shows that a tapered end thus disposed will enter the fibres more readily; or

otherwise, I may provide multiple threads in all circumstances.

It should be noted that in thisdevice, since the binding of the bristles is broken, itwill be practically impossible to remove the bristles from the handle without dispersing them, so that it will not be feasible in practice to further bind up the bristles, to pack the same and toplace them on the market. r p

In the modification shown in Fig. 2, the

tapered and threaded spindle 9 is riveted in the hand together with the'cap, is screwed upon the said spindle, so that it will expand and will exercise a strong pressure upon the cap 14. I

In Fig. 3, the sleeve 15 is slidable and rotatable on the cylindrical part of the spindle 16, and herein the screwthreaded tapered and a tapered spindle secured to the said handle and adapted to enter into the said bundle of bristles, the said sleeve comprising a cylindrical extension which is internally provided with a screw thread, the tapered surface of the said spindle being provided with a screw thread and said spinle comprising a screw threaded cylindrical extension which is adapted to be screwed into the extension of the said sleeve, the

v pitch of the screw thread of the said extension being the same as that of the one on the tapered portion of said spindle.

2. A shaving brush holder comprising a handle, a sleeve upon the said handle, the said'sleeve being adapted for the insertion of the base portion of a bundle of bound up bristles and a tapered spindle secured to the said handle and adapted to enter into the said bundle of bristles, the tapered surface of the said spindle being screw threaded, the said sleeve comprising a cylindrical extension which is hollow, the said spindle comprising a cylindrical extension adapted to enter smoothly into the cylindrical extension of the said sleeve, in such manner that the spindle is guided, but may rotate and move axially relatively to the said sleeve.

In testimony whereof I have hereunto atfixed my signature.
